The South Shore YMCA in Quincy has pushed back the opening of its new branch on Coddington Street, citing problems getting permanent power to the building.

The Y announced Thursday that the new $30 million facility won’t open until Dec. 2, more than a month after the original target date of Oct. 31. This means Quincy members will go at least three months without a city branch because the old facility, located next to the new building, has been closed since Sept. 3 after a water main break.

Y officials couldn’t be reached for comment Thursday night, but Y President Paul Gorman and Quincy branch executive Eric Snyder sent out an email to its members.

“We understand the unforeseen closure of our old facility while construction is completed has been extremely challenging and inconvenient for our members and we regret to inform you of this delay,” the email stated.

Since the Sept. 3 closure of the old building, the Y is allowing Quincy members to have access to the Emilson Branch in Hanover and any Y branches in the region. The Y is making no electronic bank drafts on monthly members until the new facility opens, and the drafts made on Aug. 30 have been refunded.
